Problem with installing sqlite3-ruby

Rails
1

Hi friends
I am new to get on the rails & I have allready a problem in installing
sqlite3-ruby.
I just made my first programme :Hello world.When I execute
http://localhost:3000/hello_world on my browser,then the following
error
comes with it.
[

no such file to load – sqlite3

RAILS_ROOT: /home/whatsup3/HelloProject
Application Trace http://localhost:3000/hello_world# | Framework

gem_original_require' /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in require’

…
]
After that I tried:gem install sqlite3-ruby then the folloing error
comes:

[

/usr/bin aren’t both writable.

Looks like you are missing the development headers for ruby. These are
often in a separate package from your linux distribution, often called
something like ruby-dev or something along those lines.

Hello,

I have this problem before. I found answer on line. Just install
sqlite3-ruby-1.2.3 instead of 1.2.4.

command is:

gem install sqlite3-ruby --version 1.2.3

hope it is helpful for you.

This way help me to fix the problem!

SQLite3:
Without the -d option, rails will default to sqlite.
To install SQLite3:
~$ sudo apt-get install libsqlite3-0 libsqlite3-dev
~$ sudo gem install sqlite3-ruby
